Telangana Sand Chrome Login Automation

I need a fast, modular Chrome extension with optional Android app integration to automate the booking process on the Telangana Sand Portal. The tool should support multi-profile autofill, OTP autofill via Android, and proxy-based multi-browser booking. Performance, reliability, and security are key.

Key Features:
Chrome Extension:
- Autofill Booking Details: Save/load multiple user profiles before booking
- Scheduled Submission: Trigger booking at specific times with retry logic
- Fast Loading: Lightweight, optimized manifest and scripts
- Multi-Booking Support: Handle multiple tabs or browser instances
- Proxy Integration: Allow proxy setup per browser/profile
- User Authentication: Secure login for extension access
- Error Handling & Logging: Robust feedback for failed submissions

Android App (Companion):
- OTP Autofill Bridge: Receive SMS OTP and push to extension via secure channel
- Local Notification & Sync: Alert user and sync OTP in real-time
- Secure Communication: HTTPS with token-based auth or encrypted payloads

Tech Stack Suggestions:
- Chrome Extension: Manifest v3, JavaScript, localStorage/IndexedDB
- Android App: Kotlin/Java, SMS Retriever API, Firebase or custom HTTPS bridge
- Proxy Support: Chrome command-line flags or external proxy manager
- Security: JWT or OAuth for user auth, encrypted OTP relay

W Ideal Developer:
You’ve built browser extensions and Android apps before. You understand civic tech quirks (dynamic forms, OTP delays, session timeouts), and you write modular, debug-ready code. Bonus if you’ve worked with proxies, automation, or booking portals.
